The Reaction Of Iron With Oxygen | Reactions …

The iron is gradually ''eaten away'' as it reacts slowly with the oxygen. Under wet conditions iron will rust more quickly. Rust is actually a mixture of different oxides of iron, but the Fe 2 O 3 of our earlier example is an important part of that. The rusting of iron is actually a good example of the process of corrosion.

Aluminium appliions – Transport

All types of vehicles, from bikes to spaceships, are made from aluminium. This metal allows people to move at breakneck speeds, cross oceans, fly in the sky and even leave our planet. Transport also accounts for the largest share of aluminium consumption: 27%. This figure is bound to keep growing over the next few years.
